Lay-Up And Recommissioning - Westerbeke 4.5 BCG Operator's Manual

LAY·UP & RECOMMISSIONING
Starter Motor
Lubrication and cleaning of the starter drive pinion is advisable,
if access to the starter permits its removal. Make sure the
battery connections are shut off before attempting to remove
the starter. Take care in properly replacing any electrical
connections removed from the starter.
Cylinder Lubrication (Diese4
.
.
If you anticipate a long lay-up period
(12
months or more)
WES'IERBEKE recommends removing the fuel injectors for
access to the cylinders. Squirt light lubricating oil into the
cylinders to prevent the piston rings from sticking to the
cylinder walls.
Make sure you have replacements for the injector and return
line sealing washers.
Intake Manifold (Gasoline]
Clean
the
filter screen in the flame arrester, and place a clean
cloth lightly soaked in lube oil around the flame arrester to
block any opening. Also place
an
oil-soaked cloth in the
through-hull exhaust
port. Make a note to remove cloths prior to
start-up!
Cylinder Lubrication [Gasoline]
Spray fogging oil into the open air intake, with the flame
arrestor removed, while the generator is running. The fogging
ail will stall out the engine and coat the valves, cylinders and
spark plugs for winter protection.
NOTE:
The spark plugs will need to be removed for cleaning
and regapping at spring commissioning.
Batteries
If batteries
are
to be left on board during the lay-up period,
make sure that they are fully charged, and will remain that
way, to prevent them from freezing. If there is any doubt that
the batteries will not remain fully charged, or that they will
be subjected
to
severe environmental conditions, remove the
batteries and store them in a warmer, more compatible
environment
A
WARNING:
Lead acid batteries emn hydrogen, a
highly-explosive gas, which can be lgnfted by electrical
arcing or a lighted cigarette, cigar, or pipe. Do not
smoke or allow an open flame near the battery being
serviced. Shut off all electrical equipment In the
vicinity to prevent electrical arcing during servicing.
Transmission [Propulsion Engine]
Check or change the fluid in the transmission as required.
Wipe off grime and grease and touch up any unpainted areas.
Protect the coupling and the output flange with an anti-
corrosion coating. Check that the transmission vent is open.
Spare Parts
Lay-up time provides a good opportunity to inspect your
WESTERBEKE engine to see if external items such as drive
belts or coolant hoses need replacement Check your basic
spares kit and order items not on hand, or replace those items
used during the lay-up, such as filters and zinc anodes. Refer
to
SPARE PARTS section of this manual.

Recommissioning
The
reco~ssioning
of your WESTERBEKE engine after a
seasonal lay-up generally follows the same procedures as
those presented in the PREPARATIONS FOR STARTING
section regarding preparation for starting and normal starts.
However, some of the lay-up procedures will need to be
counteracted before starting the engine.
1. Remove the oil-soaked cloths from the intake manifold
2.
Remove the raw water pump cover and gasket. and discard
the old gasket Install the raw water pump impeller
removed during lay-up (or a replacement, if required).
Install the raw water pump cover with a new cover gasket.
3. Reinstall the batteries that were removed during the lay-
up, and reconnect the battery cables, making sure the
terminals are clean and that the connections are tight.
Check to make sure that
the
batteries are fully charged.
A
CAUTION:
Wear rubber gloves, a rubber apron,
and eye protection when servit:lng batteries. Lead acid
batteries emit hydrogen, a highly explosive gas, which
can be Ignited by electrical arcing or a lighted
cigarette, cigar, or pipe. Do not smoke or allow an
open flame· near the battery being serviced. Shut off all
electrical equipment In the vicinity to prevent
electrical arcing dudng servicing.
4. Remove the spark plugs, wipe
clean, re-gap, and install to
proper tightness [gasoline].
5. Check the condition of the zinc anode in the raw water
circuit and clean or replace the anode as needed. Note that
· it is not necessary
to
flush the antifreeze/fresh water
· solution from the raw water coolant system. When the
engine is put into operation, the system will self-flush in a
short period of time with no adverse affects. It is
advisable, as either an end of season or recommissioning
service, to inspect the area where the zinc is located in the
heat exchanger and clear any and all zinc debris from that
area.
6. Start the engine in accordance with procedures described
in the PREPARATIONS FOR INITIAL START-UP section of
this manual. ·
